Explanation: Rajendra I (c.1014−1044 CE): Son of Rajaraja I, who carried forward his father’s expansionist policy and continued the Chola territorial expansion.

• In 1022 CE, he led an expedition to the north, crossed the Ganga following the same route which was taken by the great conqueror Samudragupta and defeated the Pala ruler, Mahipal I and the Western Chalukyas.
• To commemorate this occasion, he assumed the title of Gangaikondachola (meaning ‘the Chola conqueror of Ganga’) and established a new capital named Gangaikondacholapuram (meaning ‘the city of the Chola conqueror of the Ganga’) near the mouth of the river Kaveri.
• He built a Shiva temple here and excavated a tank called Chodagarg.
